It feels less like a formal work tool and more like a personalized communication space for the team. The UI is clean, friendly, and easy to use, but what really stands out to me is the way Slack lets people communicate beyond just plain text. Emojis, reactions, GIFs, quick replies, threads, and huddles make conversations feel more natural and expressive, especially compared to more formal workplace tools.

I also like how customizable and flexible each chat or group can be. You can pin important documents, keep useful links in a channel, react to messages, organize conversations in threads, and make a workspace feel specific to how your team actually works. Even the profile experience feels a little more human and less corporate, which makes day-to-day communication feel lighter.

Another big plus is the number of integrations. Slack connects well with tools we already use, like Gmail, Lattice, and other workplace apps, so updates and workflows can come into one place instead of being scattered across multiple platforms. Overall, Slack makes collaboration feel faster, more connected, and more personal without losing the structure needed for work. Review collected by and hosted on G2.com.

Honestly, there is not much I actively dislike about Slack. The only thing that sometimes bugs me is that Slack has so many features that I feel I am probably not using it to its full potential. For example, I would like to use Slack more as a personal document organizer or link organizer, but I do not always know the best way to set that up or build that habit.

It would be helpful if Slack prompted users more proactively with learning paths, tips, or use-case-based onboarding. For example, if someone frequently saves links or pins documents, Slack could suggest better ways to organize them, create workflows, or use features that already exist. So my issue is less about the product lacking features and more about discoverability. There is a lot of value in Slack, but I would appreciate more guidance on how to unlock it.

In my professional use of Slack, it has been one of the most-used communication platforms for sending and receiving important messages, sharing information, posting team updates, and more. Slack has an intuitive UI and visuals that make it easy to access all of its features. Slack’s upcoming AI features help me rephrase context and support other tasks as well, like taking notes. Slack’s performance is not compromised; it’s reliable, and I can pick up my chats right where I left off. The quick integrations with other platforms, such as Okta verification, Google Calendar, and Jira, are promising and effective. Overall, Slack supports my day-to-day work and helps me get things done more easily and onboarding new user is very easy. Review collected by and hosted on G2.com.

Slack notifications are very easy to miss, and sometimes they feel difficult to retrieve unless I remember the specific conversation or the team members involved. Review collected by and hosted on G2.com.

Slack completely transforms how teams connect. The UI/UX is clean and intuitive, which makes onboarding feel effortless. Where it truly shines, though, is in performance and its flawless integrations—it acts as a central hub for our entire tech stack. While the pricing is premium, the ROI from seamless collaboration and the built-in AI/intelligence search feature makes it worth every penny. Review collected by and hosted on G2.com.

When you in multiple channels the constant pings can quickly feel overwhelming and disrupt deep focus. Also the desktop app can be quite resource heavy sometime noticeably eating up RAM especially if you have multiple workspace open simultaneously Review collected by and hosted on G2.com.

What I like best about Slack is how effectively it declutters our daily internal communication. Moving conversations out of messy, endless email chains and into organized, topic-specific channels makes finding past information so much faster. It keeps the whole team aligned, and the threaded replies keep discussions focused instead of chaotic. Review collected by and hosted on G2.com.

The biggest downside to Slack is the sheer volume of notifications, which can easily lead to digital fatigue. Because it operates as a real-time chat platform, there is often an unspoken pressure to respond instantly. If you don't aggressively manage your status and notification settings, it can quickly morph from a productivity tool into a constant source of daily distraction."

Managing marketing ops means constantly coordinating across sales, demand gen, and product, and Slack has made that much easier. Dedicated channels keep everyone aligned during campaign launches, while the Salesforce and HubSpot integrations instantly notify sales when a lead qualifies. That faster handoff has helped us improve lead response time by around 40%. Review collected by and hosted on G2.com.

Notification fatigue is real, without channel discipline, everything becomes noise and important alerts get buried. Review collected by and hosted on G2.com.

Slack offers a real-time messaging service, video conferencing, and integrations with various software tools like Zoom meetings, Google Drive, and more. Slack also provides newer AI features such as summarising the context, sharing meeting notes, improved search filters, and other helpful options. It has an intuitive UI that makes it easy to start conversations without needing manual support or guidance. Overall, Slack’s performance and pricing feel suitable for big organisations that want to maintain a high-quality, real-time messaging platform. Review collected by and hosted on G2.com.

Sometimes, when messages get queued up, the conversation can feel scattered, and it becomes difficult to pull together all the information. Review collected by and hosted on G2.com.

The best thing about Slack, in my experience, is how well it keeps our team organised. We use separate channels for projects, client discussions, and internal updates, which makes it much easier to find the right information when we need it. I also like its integrations with ClickUp, Google Drive, and Sup Standup Bot because they help keep project updates in one place. Review collected by and hosted on G2.com.

One drawback is that important messages can sometimes get lost in busy channels, especially when several teams are active at the same time. Managing notifications also takes a bit of effort, since you have to fine-tune them to avoid distractions when you’re trying to stay focused. Review collected by and hosted on G2.com.

Slack’s UI/UX design strikes a nice balance between classic and modern, which gives us that comfortable sense of familiarity while we use it. The integrations have been seamless as well, and they keep us in the loop with our existing systems. Its performance and overall upkeep have made us loyal users to the point that we’ve never seriously considered migrating to another platform.

Support has also been very helpful. That said, we rarely need to contact them because the app has had little to no issues for us. I’ve seen what their AI is capable of, but our current setup isn’t really looking for an add-on like Slack AI right now. We’re perfectly content with what we have, and I’m glad Slack has been stellar for our company for the entire time we’ve had it; the ROI is evident. Review collected by and hosted on G2.com.

Nothing really. Slack has become not only our team’s main hub for communication, but also a bit of a reprieve at the same time. Review collected by and hosted on G2.com.

It keeps communication organized without slowing me down during normal workflow of the day. Review collected by and hosted on G2.com.

The main thing I dislike about Slack is how easy it is for important messages to get buried when channels become busy. Even with threads, conversations can get scattered, and I sometimes have to dig through a lot of noise to find a decision or file. Review collected by and hosted on G2.com.

I LIKE SLACK BECAUSE IT ALLOWS COMMUNICATION THROUGH OUT THE OFFICE WITH ANY ONE THAT YOU NEED TO DIRECTLY TALK/COMMUNICATE WITH. EVERYBODY CAN TYPE AT ONCE AND THE SYSTEM WILL NOT GLICH. MY FAVORITE IS THE DIFFERENT TABS THA EXPRESS THE DIFFERENT DEPARTMENTS THRU OUT THE FACILITY. Review collected by and hosted on G2.com.

THE LEAST THING I DONOT LIKE ABOUT SLACK IS THAT THE TRIAL PERIODS THAT IT HAS... REALLY DISPLAYS GOOD STUFF THAT THERE IS NO ACCESS CAPABILITY TO USE AFTER A PERIOD OF TIME. Review collected by and hosted on G2.com.
